I'm looking to add a 9mm upper to a lower I have laying around in the closet. Who makes a good, low cost upper assembly? I need the upper, barrel, and bolt. One that uses sten mags will be good, but Uzi mags will work too.

Check out the tacked topics at the top of this forum[url=http://www.ar15.com/forums/forum.html?b=3&f=15]Pistol Caliber uppers[/url]
The oly style upper uses sten mags. You can buy modified mags from oly, or you can get the SOCOM mag block that uses unmodified sten mags. Sten mags are cheap.
The colt style upper is what rra sells. It uses modified uzi mags. There is also a magblock available for the uzi mags. Uzi mags are expensive.

HUH? Sten mags are currently running about $7 used and $14.95 for slightly better they claim.
Factory Colt 32 round mags are getting $125-150. Uzi mags are averaging $15 for the 25's, and $35 for the 32's.... Add approx $10 each for somebody to notch if you plan to use a Colt pattern mag block. I went with the Hy-Tech block, as I have lots of Uzi mags for use with my Uzi, and I save the not needed notching expense for more mags. [/blue]
